Vehicular vision and alert system

ABSTRACT

A vehicular vision and alert system includes a camera disposed at a windshield of a vehicle so as to have a field of view forward of the vehicle as the vehicle travels along a traffic lane of a road. As the vehicle travels along the road, the system may determine, via processing by an image processor of image data captured by the camera, traffic traveling along another traffic lane and may generate a traffic alert indicative of the determined traffic. As the vehicle travels along the road, the system may determine, via processing of captured image data, a vehicle accident involving another vehicle and may transmit an accident alert communication to a remote system. As the vehicle travels along the road, the system may determine, via processing of captured image data, a traffic jam index representative of a degree of traffic traveling along the other traffic lane.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

A vehicle vision system and/or driver assist system and/or object detection system and/or alert system operates to capture images exterior of the vehicle and may process the captured image data to display images and to detect objects at or near the vehicle and in the predicted path of the vehicle, such as to assist a driver of the vehicle in maneuvering the vehicle in a rearward direction. The vision system includes an image processor or image processing system that is operable to receive image data from one or more cameras and provide an output to a display device for displaying images representative of the captured image data. Optionally, the vision system may provide a top down or bird's eye or surround view display and may provide a displayed image that is representative of the subject vehicle, and optionally with the displayed image being customized to at least partially correspond to the actual subject vehicle.

Referring now to the drawings and the illustrative embodiments depicted therein, a vehicle 10 (the subject vehicle or SV) includes an imaging system or vision system 12 that includes at least one exterior facing imaging sensor or camera, such as a rearward facing imaging sensor or camera 14 a (and the system may optionally include multiple exterior facing imaging sensors or cameras, such as a forwardly facing camera 14 b at the front (or at the windshield) of the vehicle, and a sidewardly/rearwardly facing camera 14 c, 14 d at respective sides of the vehicle), which captures images exterior of the vehicle, with the camera having a lens for focusing images at or onto an imaging array or imaging plane or imager of the camera (FIG. 1). The vision system 12 includes a control or electronic control unit (ECU) or processor 18 that is operable to process image data captured by the cameras and may provide displayed images at a display device 16 for viewing by the driver of the vehicle (although shown in FIG. 1 as being part of or incorporated in or at an interior rearview mirror assembly 20 of the vehicle, the control and/or the display device may be disposed elsewhere at or in the vehicle). The data transfer or signal communication from the camera to the ECU may comprise any suitable data or communication link, such as a vehicle network bus or the like of the equipped vehicle.

The traffic jam monitor and update module of the present invention is connected to a plurality of vehicle cameras, including a windshield camera 101 and other exterior viewing cameras 105 (SV cameras), and is connected to a vehicle network bus 109 (such as a vehicle CAN bus) and a remote service 110, such as a cloud service) using high speed data 108 (4G/LTE/5G)//V2X link 115, such as shown in FIG. 2. The module or system may include a control or ECU 106 that is in communication with the windshield camera 101 via a link or connection 114 and with the other SV cameras 105 via respective links or connections 107. The control may also communicate via a designated short range communication (DSRC) for the V2V or V2X link 115. The cloud service 110 communicates with other devices, such as a mobile device or smart phone 112 and other vehicles 111 (via wireless communication links 113).

Using the windshield and SV cameras (which may include sideward viewing cameras and/or rearward viewing cameras or the like), the traffic jam monitor and update (TJMU) algorithm detects traffic jam situation via image processing of image data captured by the vehicle cameras.

The TJMU algorithm utilizes the captured image data and the driving pattern of the subject vehicle (such as the SV braking, accelerating and vehicle speed, pitch, yaw, roll and/or the like) and computes a traffic jam index between 0-10, where 0 is representative of a very low traffic jam (little to no traffic) and 10 is high (many vehicles on the road being traveled by the SV).

The TJMU algorithm and system transmits the SV location information (such as using a GPS system of the subject vehicle to determine the SV location) and the determined traffic jam index at real time using the high speed data link or V2X link to provide a real time traffic alert cloud service.

Subscribed users (users of mobile devices or vehicles 206, such as the user of the vehicle (SV) in FIG. 3) for the real time traffic alert cloud service then receive the real time alert of the traffic situation. The subscribed users may only receive the alerts if the particular user is at or near or approaching the determined traffic jam location (such as within two miles of the traffic jam location or within a mile of the traffic jam location or within a ½ mile of the traffic jam location or thereabouts) or is following a navigation route that intersects or approaches the determined traffic jam location.

In many situations, it will be better if the users are alerted of a traffic jam in the freeway in advance before the user enters the freeway. As can be seen with reference to FIG. 4, the TJMU algorithm of the present invention (as shown in the subject vehicle SV) may be operable to detect a traffic jam condition of oncoming traffic 204 in the freeway using the windshield camera 101 and may generate an alert and communicate the alert using the V2X (such as V2V or V2I) link to alert the traffic that is about to enter the freeway. The system may determine a traffic jam or traffic condition or accident involving other vehicles on another road or lane near the road being traveled by the vehicle, such as on lanes of a highway or freeway with traffic moving in the opposite direction of the subject vehicle, or other vehicles on another road that intersects the road being traveled by the subject vehicle.

Optionally, and with reference to FIG. 5, the TJMU algorithm may detect an accident scenario 203 (such as an accident involving one or more other vehicles in a lane 202 adjacent to the lane 201 traveled by the subject vehicle SV) utilizing the windshield camera 101 and may update the information to the cloud in real time along with the GPS location information. For example, an accident alert or communication (pertaining to a determined accident involving another vehicle or vehicles) may be periodically transmitted to the remote server or cloud to provide updates on the accident or traffic condition. The accident alert may include information pertaining to the accident, including geographical location information pertaining to the location of the accident (such as determined via a GPS system of the vehicle).

As can be seen with reference to FIG. 6, the module 116 determines the traffic jam scenario depending on the driving pattern of the driver (such as application of the vehicle brake pedal or accelerator pedal and the vehicle speed, pitch, yaw and/or roll, such as may be determined by one or more sensors of the vehicle) with respect to the speed limit information, and outputs the traffic jam index output 118. The traffic flow and accident scenario determination module 117 utilizes the windshield camera and surround view system camera and determines the traffic jam index 119. The traffic jam intensity detector module 121 fuses the outputs of the modules 116, 117, and generates the final traffic jam intensity index 122 which will be transmitted to the cloud or V2X infrastructure via V2X/Cloud interface 123 in real-time. The traffic alert may be periodically transmitted to provide updates as to the traffic jam level or index (such as current speed of travel of vehicles in the traffic jam or the like), with the updates including the current geographical location of the vehicle and traffic jam. Responsive to a determination of an accident by the module 117, the accident may be reported via communication 120 to the cloud or V2X infrastructure via V2X/Cloud interface 123.

Thus, the present invention provides a system that determines a traffic condition ahead of and on the road being traveled by the equipped vehicle and, if the determined traffic condition is indicative of a threshold level of a traffic jam (such as, for example, if the traffic rating or index is above a 5), the system generates a communication via the V2I link to the remote server or service, whereby other users of the system may receive an alert of the traffic jam condition. For example, another user may receive the alert if the other user is at or near the traffic jam location or following a selected path towards the traffic jam location or the like. The system may also utilize a V2V communication link to communicate immediate traffic jam conditions to vehicles in the vicinity of the equipped vehicle, such as to alert the drivers of other vehicles of a traffic jam on a highway, so that the other drivers can avoid entering the on-ramp of the highway.

The vehicle communication systems may utilize aspects of the systems described in U.S. Pat. Nos. 6,690,268; 6,693,517; 7,156,796 and/or 7,580,795, and/or U.S. Publication Nos.

The camera or sensor may comprise any suitable camera or sensor. Optionally, the camera may comprise a “smart camera” that includes the imaging sensor array and associated circuitry and image processing circuitry and electrical connectors and the like as part of a camera module, such as by utilizing aspects of the vision systems described in International Publication Nos. WO 2013/081984 and/or WO 2013/081985, which are hereby incorporated herein by reference in their entireties.

The system includes an image processor operable to process image data captured by the camera or cameras, such as for detecting objects or other vehicles or pedestrians or the like in the field of view of one or more of the cameras. For example, the image processor may comprise an EYEQ2 or EYEQ3 image processing chip available from Mobileye Vision Technologies Ltd. of Jerusalem, Israel, and may include object detection software (such as the types described in U.S. Pat. Nos. 7,855,755; 7,720,580 and/or 7,038,577, which are hereby incorporated herein by reference in their entireties), and may analyze image data to detect vehicles and/or other objects. Responsive to such image processing, and when an object or other vehicle is detected, the system may generate an alert to the driver of the vehicle and/or may generate an overlay at the displayed image to highlight or enhance display of the detected object or vehicle, in order to enhance the driver's awareness of the detected object or vehicle or hazardous condition during a driving maneuver of the equipped vehicle.

The vehicle may include any type of sensor or sensors, such as imaging sensors or radar sensors or lidar sensors or ladar sensors or ultrasonic sensors or the like. The imaging sensor or camera may capture image data for image processing and may comprise any suitable camera or sensing device, such as, for example, a two dimensional array of a plurality of photosensor elements arranged in at least 640 columns and 480 rows (at least a 640×480 imaging array, such as a megapixel imaging array or the like), with a respective lens focusing images onto respective portions of the array. The photosensor array may comprise a plurality of photosensor elements arranged in a photosensor array having rows and columns. Preferably, the imaging array has at least 300,000 photosensor elements or pixels, more preferably at least 500,000 photosensor elements or pixels and more preferably at least 1 million photosensor elements or pixels. The imaging array may capture color image data, such as via spectral filtering at the array, such as via an RGB (red, green and blue) filter or via a red/red complement filter or such as via an RCC (red, clear, clear) filter or the like. The logic and control circuit of the imaging sensor may function in any known manner, and the image processing and algorithmic processing may comprise any suitable means for processing the images and/or image data.
